2019 GMC Acadia

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The issue was with the gear select switch and jumper harness, related to the "Shift to Park" malfunction in my 2019 GMC Acadia. Yes, the components were available at the time of the repair with the GMC dealer. 2. How was your safety or the safety of others put at risk? The vehicle would not recognize when it was in "Park," which prevented it from being turned off. This could lead to unexpected vehicle movement or battery drain, and creates a safety risk if the driver assumes the vehicle is secure when it is not. It also poses a hazard if the vehicle cannot be safely shut down in an emergency or in unsafe conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was reproduced and confirmed by a GMC dealer during an appointment on July 22, 2025. They diagnosed the problem and verified that the gear select switch and jumper harness needed replacement. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle was inspected and repaired by an authorized GMC dealer. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No, a "Shift to Park" warning message appeared and the vehicle would not allow me to turn it off without shifting in and out of park multiple times. This first occurred on July 18, 2025, and continued until the repair was made.

On my 2019 Acadia, the message shift to park keeps appearing on my dash when I shirt the car into parked. It's getting more frequent and when I called GMC it's a well known problem to where the lady taking my appointment says yes we are aware it's happening alot. They want to charge 800 to fix a problem that should be a recall. It's a well known problem and there has been cases and suits brought up and GMC will not make a recall on this even though the mechanic said I can't believe this hasn't been recalled. Can you help with making GMC do a recall in the Shift to Park. Thank You

The contact owned a 2019 GMC Acadia. The contact stated that while driving at 20 MPH and attempting to adjust the steering wheel, the steering column and the steering wheel detached and fell in the contact’s lap. No warning light was illuminated. A dealer was contacted. The vehicle was taken to the dealer, where it was diagnosed, and determined that the steering column and steering wheel needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 125,298.

When I park and then turn the car off the car fails to recognize that the gear shifter is in the park position. As a result, the car doesn’t fully shut down, leaving the engine running or the electronics active. This drains the battery. I have seen this issue is recalled for other 2019 Acadias but don’t under why it is not recalled in mine. I’m afraid I’ll be out and about and unable to turn my car off resulting in a dead battery and being stranded.
